ing upwardly around the boiler tubes. By

virtue of the gradual reduction in diameter of the pipe, less obstruction is presented to the flow of the furnace gases than is possible where the pipe is -of the same diameter throughout its length and it thereforevconst itutes a further advantage of my invention that the element effects a dimunition of the resistance to the flow of the furnace gases. Y

That I claim as my invention is l. A tubular blower with a series of discharge nozzles distributed along its length for discharging a cleaning Huid adjacent parts of a boiler to be'cleaned, said blower element diminishing in diameter element provided 'i from one of its ends to the other so that erativelyy associated with the boiler the resistance-to the flow of furnace gases will be diminished.

3. The combination with a boiler having a plurality of tubes, of a tubular blower eleinent positioned within said boiler, said element being formed of a heat resisting alloy and provided with a series of discharge nozzles :distributed along its length for discharging a cleaning fluid toward the boiler tubes for cleaning said tubes, said blower diameter from one of its ends to the other.

In testimony whereof I aiix my signature.
